Service Report May 2021 Colorectal and Peritoneal Oncology Centre – The Christie NHS Foundation Trust

1. Introduction The Christie Colorectal and Peritoneal Oncology Centre (CPOC) Peritoneal tumour Service (PTS) experienced a reduction in referrals with regard to the appendiceal tumour activity compared to the year 2019-2020 (259 and 278 respectively); whereas the referrals concerning patients with colorectal peritoneal metastases (CRPM) marginally increased (198 versus 196 respectively). This translated into 121 appendiceal procedures and 67 CRPM procedures, compared to 130 and 62 respectively in 2019-20. Considering the need to provide an additional 70 colorectal cancer resections whilst acting as a Covid “green site” for Greater Manchester, as well as the restrictions placed on the unit due to the Covid-19 pandemic, the team have worked extremely effectively in often very challenging circumstances over the last year. We have been delighted to welcome our 2 new consultant colleagues, Rebecca Fish who joined in October 2020 and Paul Sutton who joined in February 2021. In addition, we were joined by the 1 st ACPGBI/RCS Advanced Colorectal Malignancy fellow Sarah Hassan who is spending a year from October 2020 with us. We currently have 5 of our staff undertaking the ESPO fellowship in peritoneal surgery. Our results continue to indicate a high-quality service. For those with appendiceal neoplasia undergoing CRS and HIPEC, 77.9% have had a CC0/1 cytoreduction and patients with colorectal peritoneal metastases 83.6% had CC0/1 cytoreductions. Overall, our minor and major complication rates remain within and compare favourably to the internationally published data, with 29.2% having minor (G1/2) complications and 13.8% having G3/4 complications over the past 12 months. There was a single (0.52%) 90-day mortality. The unit has now performed 81 laparoscopic risk-reducing CRS+HIPEC with no complications in 80.3%, 6% G3/4 complications and no 90-day mortalities. 5-year overall survival in patients with benign appendiceal, malignant appendiceal and colorectal peritoneal metastases are calculated to be 86%, 64% and 37% respectively. We now have sufficient data to produce Kaplan Meier curves up to 72 months’ post treatment. As in the rest of the NHS, The Christie Hospital has been significantly affected by the Covid 19 pandemic. Thankfully there have been relatively few infected patients that have passed through the trust. By pursuing a very careful level of biosecurity that has included all staff wearing PPE in all clinical areas and undergoing weekly swabbing to detect Covid (PCR tests), all in-patients being swabbed within 5 days of any surgical procedure and then again on days 3 and 7 post-operation, admitting the majority of patients on the day of their surgery, prevention of all visitors and a dramatic increase in the number of remote consultations, using telephone and video communications, we have only needed to close the main ward on a single occasion for 8 days in December. We have had a successful year with regard to our research and training activities in spite of being unable to visit meetings or other units. Over 2020-2021 the group has obtained nearly £4million of funding for a variety of projects, both clinical and laboratory based. The unit has published 18 separate papers in peer reviewed journals since 2019. Our charity continues to provide us with significant support to allow us to develop our research and also to add to our patients’ and their families experience. MS Wilson May 2021

Consultants We have 8 WTE consultants. In the last year we have expanded our consultant workforce with the appointments of Rebecca Fish, who joined us in October 2020, and Paul Sutton who started his post in February 2021. Professor Sarah O’Dwyer has decreased her clinical commitments in 2020 2021 to allow time for academic pursuits which will include projects dedicated to investigating

potential novel treatments for PMP. Clinical Nurse Specialists (CNS) This team has continued to remain stable over the past 12 months. Admin/Secretarial service

We successfully recruited Paul Diez Echave as Data Manager who has replaced Jacinth Kilmartin. We now have full complement of medical secretaries with further cross-cover required in order to provide secretarial support for the new consultant appointments. Managerial staff Although the managerial staff have remained stable during the last 12 months, our service manager covers other roles across the surgical division, and we still do not have a dedicated PTS manager.

Infrastructure development Through a joint venture with The Christie NHS Foundation Trust and HCA The Christie Private Care, there has been an increase in operating theatre capacity with two new operating theatres going live in October 2020. These theatres are fully integrated with the state-of-the-art Olympus ENDOALPHA system, including 4K ultra high-definition, 3D and fluorescent imaging capabilities in addition to the nCare and VaultStream image recording and medical content management system. The new theatres have increased the number of surgical theatres to 7 in addition to separate endoscopy and day case theatres. In addition, a new day of surgery unit (DOSA) also opened in August 2020 with an increasing number of selected PTS patients now being admitted on the day of surgery. A significant infrastructure development at The Christie is the £150M Paterson Redevelopment Project. Despite the COVID-19 pandemic, building work continues on this new world-class transformational cancer research facility which will be one of the largest of its kind in Europe and will provide an exciting opportunity for members of CPOC to collaborate with leading cancer research scientists and help fulfil the unit’s research ambitions. It is anticipated the Paterson Building will be completed in 2023.

3 Impact of Covid-19 pandemic In March 2020 a global pandemic was acknowledged and NHS England issued guidance for preparation of The NHS to prepare for the exponential rise in cases expected based on the epidemiology of the disease noted from countries in Asia and Europe. The re-allocation of workforce and estates to increase ventilator capacity had a significant consequence for the elective surgical services. At The Christie, anaesthetic services were significantly affected due to re-deployment in support of acute COVID sites. The operating capacity for the CPOC team suffered a 45% reduction in operating theatre capacity. In parallel NHSE, the Royal Colleges and professional associations issued guidance relating to surgical practice during the COVID pandemic. This led to the adoption of NHSE guidance for prioritisation for surgery defined as: - • Priority level 1a: emergency operation needed within 24 hours to save life • Priority level 1b: urgent operation needed with 72 hours • Priority level 2: elective surgery/treatment with the expectation of cure needed within four weeks to save life/stop progression, taking into account symptoms and potential complications from lack of treatment • Priority level 3: elective surgery can be delayed for 10 to 12 weeks and will have no predicted negative outcome We agreed that P1 and P2 cases would continue but also recognised that a significant number of the Highly Specialised and Specialised commissioned case load fell into the P3 group. Cases were evaluated through the MDT and listed for the surgery as dictated by their disease independent of COVID and allocated a P level. Towards the end of April 2020, Greater Manchester Cancer created a Surgical Hub service to allow time critical cancer surgery to be offered on a ‘Covid free’ site. The Christie became the designated site to treat patients requiring Level 2/3 post-operative critical care support. During this time 70 primary colorectal cancer patients were operated on by Christie colorectal consultants at The Christie who would normally be operated on by other providers. As there had also been NHSE guidance regarding cancer treatments during the pandemic, which included deferring systemic anti-cancer treatment unless considered time critical, the peritoneal MDT concluded that it would be best to suspend HIPEC but that it remained appropriate to offer CRS in individual cases of appendix and colorectal cancer. We took the decision to stop using HIPEC in all of our patients on 8/4/20, with the last case to receive HIPEC being operated on in late March. We restarted HIPEC on 18/5/20 after achieving a consensus from the other UK and some European sites. Since that date all HIPEC procedures have been performed using the “closed technique” in order to reduce the risk of aerosol generation. This has now become the new normal for our surgeons. Following this change in practice we are now undertaking a comparative audit of closed versus open HIPEC delivery to ensure patient safety. Provision of the service continued apart from a break when all major surgical, non-emergency activity was stopped for 2 weeks to allow control to be achieved of an outbreak of Covid on the surgical ward in December 2020. No patients had significant damage as a result of catching Covid

Service Report May 2021 Colorectal and Peritoneal Oncology Centre – The Christie NHS Foundation Trust

and there have been no further cases since this. No patient receiving cytoreduction and HIPEC contracted Covid whilst being an in-patient at the Christie. All patient facing staff at The Christie are tested once a week with PCR tests, patients are tested prior to admission to the hospital, on admission and once a week thereafter whilst an inpatient. This protocol has allowed us to largely maintain a Covid secure environment and allowed the outbreak on the surgical ward to be rapidly identified and controlled. Once we had restarted the HIPEC service the level of surgical cytoreductive activity returned to pre-covid activity levels with operative monthly activity returning to the same rate as 2019/20 after the initial period in May when activity was reduced with the total level of activity being 121 in 2020/21 vs 130 in 2019/20 and 102 in 2018/19. Referral activity for the specialist commissioned services was consistent throughout the Covid period compared to the 2 previous years. This probably reflects that these patients are diagnosed either by being symptomatic or as a result of appendix specimen histology following emergency appendicectomy. CRPM activity, including both referrals and surgery, reduced during the initial phase of the pandemic. This may have reflected the delay of surveillance scans undertaken on these patients in their local hospitals after their previous surgery. The level of referrals has increased since the beginning of 2021 but the total number of referrals is still down for 2020/21 (144) vs 173 for 2019/20 and 187 for 2018/19. By the end of March 2021, the number of CRPM cytoreductions with HIPEC was 67, compared to 62 over the same period in 2019-2020.

4 Patient and Public Engagement

4.1Patient Day Since 2016 we have been holding an annual patient day at The Christie. We had 113 registered for our patient day in April 2020, but sadly this could not go ahead due to COVID-19. In April of this year, the same restrictions applied and we held our support day virtually so our patients still felt supported in some way. We had 3 patients attend our auditorium to share their stories, presentations from our physiotherapists, a clinical psychologist and Consultants from the team. The day included a live question and answer session. 34 patients signed on virtually and despite not being able to network with each other, we received overwhelmingly positive feedback. As a result of this, when we can resume our support day face to face, we will continue the virtual platform alongside it so those who cannot make it to The Christie can still benefit from the day. Our next day is planned for the 21 st of April 2022. Here are some of the comments from our first virtual patient support day: “Once again a very interesting and moving day. Stories of hope and courage that inspire. The day makes me feel like I’ve got a support network that is so comforting. The dedication of the Christie Team is humbling. Thank you to Rebecca for creating a platform that we are able to express ourselves, understanding our disease and treatments available.” “Great to hear other peoples’ journeys as they differ so much yet also have so much in common. Helps me to feel less isolated”. “A great event! Event was well thought through and executed. An enjoyable and insightful day!” “This was my first patient day and I am so impressed. It’s given me a real lift and made me feel so much more empowered in my treatment and care.” “Very informative, supportive and uplifting. In the absence of not being able to arrange a face to face day, this was the next best thing.” “Great having it online as I live 350 miles from Christie's” “We found the day extremely informative and helpful, hopefully next year we will be able to “The day lacked the important issue of "mingling" and sharing experiences with others which can be really supportive. However, in the circumstances the on line day was excellent” “Really useful blend of the medical information/expertise and patient experience” “Stories of hope and courage that inspire” “It made me feel so much more empowered in my treatment and care” “Given the difficult circumstances the patient day was an absolute success, well done to everyone involved” meet face to face and exchange experiences” “Very informative supportive and uplifting”

4.2Nurse led follow up service Our telephone follow-up service was set up in 2013 and this is now completely nurse led. 629 Clinical Nurse Specialist (CNS) follow up consultations were performed in the last year. We have sent out a satisfaction survey to 106 patients on the 20 th of April 2021 in order to identify possible unmet needs of patients and to see if we can improve the clinics further. We now offer this service

14

Service Report May 2021 Colorectal and Peritoneal Oncology Centre – The Christie NHS Foundation Trust

virtually via the NHS video conferencing link and it has been positively welcomed by many patients. The CNS’s now have a nurse led clinic twice a month which is done face-to-face. Due to COVID 19 it has been done over the telephone or virtually. This is a good opportunity for patients to have some time with their CNS to not only discuss their results and follow up but any issues they may be having that are affecting their quality of life. The clinics are also used to discuss the holistic needs assessment completed by patients prior to their appointment, formulate a care plan with the patient and sign post them to supportive services. 4.3ePROMS (electronic Patient Related Outcome Measure Service) The Christie have developed an electronic quality of life questionnaire using a platform called ePROMS to improve patient outcomes. This enables patients to complete the questionnaire using a specific online application which is quick and easy to use. An example of a typical question frame is shown below: -

The answers are colour co-ordinated with a key providing patients with advice if they are having problems which they should seek help for. The peritoneal tumour service has been one of the first to bring this to surgery and it will be piloted on patents operated on between 2019 and 2020 in June 2021. The results can be accessed by Clinicians via the individual patient’s records on our patient portal (CWP). Going forward patients will then receive this at years 1, 3, 5 and 10.

5 Education and Training, Research 5.1Education and Training

There is no doubt that the COVID situation has had a major impact on education and training with many of the professional meetings postponed/ suspended during 2020. Despite these difficulties we have managed to recruit to our Clinical Fellowships both in the UK and overseas. In 2020 we were successful in a bid to launch a new Fellowship: RCS/ACPGBI Advanced Colorectal Malignancy Fellow branded through the Royal College of Surgeons and the Association of Coloproctology of GB&I. The current fellow Sarah Hassan will complete her term in September 2021. We continue to support International fellows from India through The Ganga Ram Fellowship programme and from Sri Lanka: all of which have continued despite Covid restrictions. European Society of Surgical Oncology (ESSO) ESPO Fellowships: The unit has been designated by ESSO for Training in Peritoneal Oncology. Since 2015 there have been 9 Fellows registered at The Christie: • EPSO/ESSO Graduates : Andreas Larentzakis Washington November 2016: Consultant Surgeon in Greece. Adam Stearns, Paris September 2018: Consultant Surgeon in Norwich Paul Sutton, February 2021: Consultant at The Christie NHSFT • Current Fellows : Hamish Clouston, Jonathan Wild, Rebecca Fish: Consultants at The Christie Brett Winter-Roach and Rebecca Faulkner: Consultant Gynaecologists. Some progress has been hampered by the restrictions due to Covid for ESSO to run courses but it is expected that the Fellows should graduate over the next two years. The RanD Academy Unfortunately, we have been unable to collaborate during Covid for most of the major projects in this programme. However, the relationship with The King Hussein Cancer Centre in Amman, Jordon sponsored by The RanD Academy has continued through the completion of a twelve month clinical fellowship by Basim Aljalabneh. In June 2020 Professor O’Dwyer was also invited to speak in an international Webinair discussing the Prodige 7 trial debating the influence of the trial and implications for HIPEC. In March 2021 Professor O’Dwyer was nominated by The Dukes Club ACPGBI as an inspirational trainer and pioneer for surgical treatment of peritoneal tumours.

Over the past year we have established The Christie Colorectal and Peritoneal Oncology Centre (CPOC) Academy and Lab, at the Manchester Cancer Research Centre. Despite the challenges of the pandemic, we have grown our collective research team which now comprises of; 5 PhD students, an academic clinical lecturer (50% clinical/50% academic), 2 postdoctoral research fellows, and a research manager. This team is funded through the grants listed in section 5.5. Our key research themes include: (i) Biomarker research (ii) Technology and Innovation (iii) Clinical outcomes and treatment effects 5.2.1Biomarker research Cancer Research UK Accelerator Award: Pseudomyxoma peritonei: building a European multicentric cohort to accelerate new therapeutic perspectives – We are one of three European groups (including Italy and Spain) that have been awarded this prestigious award to accelerate the collection of a comprehensive biobank of tissue from patients with pseudomyxoma peritonei (PMP) from Low-grade appendiceal mucinous neoplasms (LAMNs) over 5 years. The £2.5m award aims to identify genomic biomarkers, build in vitro 3-D models and organoids, and ultimately establish a platform to identify therapeutic options for PMP patients. Our team includes faculty from across The University of Manchester including; CPOC Lab at The Manchester Cancer Research Centre, Wellcome Trust Centre for Cell Matrix, School of Pharmacology, and Manchester Centre for Genomic Medicine. The project has to date established a standardised biobank collection process, tumour sampling, DNA and RNA extraction across the 3 countries. We are now looking to standardise live tissue processing and cell culture leading to the development of LAMN in vitro models and organoids. Ultimately this project will lead to the establishment of libraries of information that can be shared with researchers across the world to accelerate our understanding of LAMNs leading to PMP.

Dysregulated pathways in ColoRectal cancer Peritoneal Metastasis (CRPM): Funding secured from The Christie Charity has allowed us to establish our CRPM biomarker research program. Our comprehensive analysis of samples from peritoneal metastases with their matched colorectal cancer primaries obtained during cytoreductive surgery has been tested and validated leading to the identification of 20 genes dysregulated in peritoneal metastases that promote an early increasing role of "stemness" in conjunction with tumour favourable inflammatory changes. Our findings have indicated that the activation of these pathways, and adaptation to the peritoneal-specific environment are key to early stages of peritoneal metastasis. We are now focusing on increasing our sample size, looking for prognostic signatures, and exploring these pathways to look for therapeutic options. 5.2.2 Technology and Innovation Mass Spectrometry to characterise lipid profiles of CRPM: Mass spectrometry is a very powerful tool, used to rapidly and reliably characterise tissue. We have established a partnership between Waters Corporation (A leading mass spectrometer manufacturer), The University of Manchester, and The Christie CPOC to characterise colorectal peritoneal metastases using this powerful tool. Funded by the Medical Research Council, we have a PhD student whose project involves characterising the lipid profiles of these tumours. This is a platform for future research in this area which has implications not only for the understanding of the peritoneal environment as a metastatic site, but also for the development of rapid tools that tell the surgeon in real-time whether a tissue is ‘tumour’ or ‘normal’. The project aims to have a mass spectrometer installed in an operating theatre for real-time tissue characterisation. Prehabilitation with wearables before CRS/HIPEC: A randomised controlled pilot study. Having undertaken a systematic review of prehabilitation programs in abdominal cancer surgery, we have designed and completed the first randomised controlled trial of prehabilitation delivered solely with wearable devices versus standard of care in patients undergoing CRS/HIPEC. Funded through a donation from the charity ‘Pseudomyxoma Survivor’, we were able to achieve 67% recruitment. The prehabilitation group engaged in more daily minutes of moderate and vigorous physical activity compared to controls. They also had significantly greater improvements in the distance they could walk in 6 minutes compared to controls (+ 85.6 m vs + 13.23 m, p = 0.014]. We are now in the process of designing a larger randomised control trial in this group to quantify the impact of this improvement on post-operative recovery. 5.2.3 Clinical outcomes and treatment effects EVidencE Review of PEritoneal Tumours (EVERPET) This a 3-year NIHR-funded project between University College London and The Christie CPOC that started in 2019. This project aims to comprehensively evaluate the evidence for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal metastases of colorectal, ovarian, gastric and appendiceal origins through individual patient data meta-analysis of clinical We continue to publish and share our outcomes with the international community. Projects include indications and outcomes for repeat CRS/HIPEC in peritoneal surface malignancy, Referral pathways and outcome of patients undergoing CRS/HIPEC, and Radiological patterns of recurrence after CRS/HIPEC for CRPM. Early identification of LAMNs at risk of PMP: We have one of the world’s largest patient groups with early LAMNs referred through our established network over the past decade. Our research in this area includes: The Long-term outcomes for pTis and pT3 non-perforated LAMNs on an active surveillance pathway and trials.

We are extremely grateful to all of our donors for their unfailing support and generous donations. These are some of the achievements and future opportunities: - 6.1 Increased awareness has resulted in more referrals Better understanding of the appendix as the source of disease has led more professionals and patients to check the pathology in the appendix and request information and referrals to the reference centres. Earlier referral has led to a greater proportion of patients being seen with localised and less advanced disease. This has allowed us to offer preventative surgery now described as ‘risk reducing’ surgery to stop the development of full blown PMP. In a number of cases this surgery can be performed using keyhole techniques which have been pioneered at The Christie. Specialist equipment is required to undertake these procedures and video transmission of the procedures has been created to educate other centres in these techniques. Using these methods patients have a shorter stay in hospital and return to work and full activity much quicker. Charitable funds have allowed the purchase of additional surgical equipment which in turn facilitate We recognise that the diagnosis and treatment of patients with PMP and appendix tumours has specific stresses. This is often because the conditions are rare and those dealing with it feel isolated and unsupported by the professionals and the NHS. Identifying where and when in the journey the key milestones are, allows us to direct resources to support patients. We have identified financial burdens on families and are working with charities to offer accommodation for families and supporters during hospital spells. In addition, support with transport to attend for tests and treatments takes the worry from those with limited resources. In particular, through support from the Pseudomyxoma Survivor charity, we have been able to agree a contract with StayCity, Manchester to provide offsite accommodation for patients’ families whilst they undergo their inpatient treatment. In addition, Pseudomyxoma Survivor have donated gift boxes for patients on the ward to help improve their stay. the development and use of novel surgical procedures. 6.2 Improving the patient journey and experience
